Title: Extended nip press apparatus with geared blanket edge clamp
Inventor: DIDIER JAMES J
IPC: D21F3/00
Filed: 1996-05-13
Abstract: In an extended nip press employing an endless loop nip blanket the invention is a gear-actuated blanket edge clamp. The ends of the blanket are sealed to rotatably mounted heads and forced against sealing surfaces on the heads by shoes which are mounted radially about the heads. The shoes are pivotally mounted to main pivot links. These in turn are pivotally mounted to the head. A jack link joins each of the main links to an expanding gear ring. The gear ring is rotatably mounted to the head about the axis of the head's rotation. The gear ring has two opposed gear teeth segments. Two opposed pinion gears which are mounted on shafts ride on the geared sections. The shafts are turned from the exterior of the head, and cause the expanding gear ring to rotate. The rotation of the gear ring causes the jack links to press against the main links,causing the main links in turn to swing radially outwardly. The outward displacement of the main links causes the shoes to move outwardly against the clamping surface. A gear clamping ring is disposed inwardly of the gear ring andshoes, and is arranged to secure the shoes and ring gear against movement. During operation of the extended nip press, the blanket is held taut by internalpressure. In an alternative embodiment the jack links have spring biasing to accommodate variations in link dimensions.

Patent CA-2183715-A1 (CA)
Title: Device and method for locating faults in a paired line
Inventor: CRICK ROBERT G
IPC: G01R31/08
Filed: 1996-08-20
Abstract: A device and method are provided for locating faults in a paired line.  The fault locating device has a base unit and a terminator unit connectable to the conductors of a paired line containing the fault.  The device also has a portable locator unit movable along the paired line between the base unit and the terminator unit.  The locator unit contains a coil positioned at the paired line for coupling an induced signal thereon.   The base  unit  and  terminator  unit  each  contain  circuits  for receiving the induced signal from the locator unit and measuring a selected characteristic of the induced signal.  The base unit additionally has a circuit for creating a base carrier signal having the selected characteristic measured at the base unit and terminator unit encoded thereon.   In operation, the base unit sends the encoded base carrier signal to the locator unit which decodes and continuously communicates values of the induced signal characteristic to the operator by means of an audible or visual indicator.  The operator incrementally repositions the locator unit away from the base unit and toward the terminator unit as operation of the device proceeds.  When the locator unit approaches  the  fault,  the  intensity  and  frequency  of  the indicator remains relatively stable except for some variation due to conductor twist and relative coil position.   When the locator unit passes the fault, however, such that the fault is between the locator unit and the base unit, the intensity or frequency of the indicator abruptly drops, thereby establishing the precise location of the fault.

Patent CA-2188570-A1 (CA)
Inventor: FRIEDHELM STEFFEN
IPC: E06B3/62
Filed: 1996-02-13
Abstract: The invention relates to a sealing profile 1 for plastic, metal, and even wooden windows that is able to cover large gaps because the sealing lip 13 and the sealing gap 12 are of a specific form and occupy a specific position.  Also, it is able to do this by the fact that they are comprised of different soft and hard plastic materials.  The sealing lip 13 and the sealing pad 12 are arranged at a V-shaped incline in relation to one another, with the boundary surface 14 between the softer material of the sealing pad 12.  The harder material of the sealing lip 13 then extends very close to the sealing lip 13 on one side and to the anchoring wedge on the other.  In addition to the security of being able to span large gaps without problems, the sealing profile 1 also provides the advantage of being able to be completely mounted in corners without difficulty.  It also ensures that a secure seal is created since the sealing pad 12 and the sealing lip 13 become properly molded when installed against the glass pane 2.
Patent CA-2190547-A1 (CA)
Title: Multilayer structures and process for fabricating the same
Inventor: CHOI JAE HONG
IPC: B32B7/03
Filed: 1996-11-18
Abstract: A substantially warp-free laminate polymeric film structure is obtained by a fabrication process in which the individual layers of polymeric film that are to be laminated together to form a card or similar structure are selected such that the mechanical properties of one layer or pair of layers are offset by those of another layer or layer pair. The properties of the layers which may be subject to this consideration include, for example, the layer thickness, tensile strength, elongation factor, shrinkage rate, and machine processing direction. In an illustrative three-layer substrate embodiment of the present invention, the tensile strength, elongation factor, and shrinkage rate of the outer film layers of the substrate are the same, with the outer layers having a higher tensile strength value than the inner layer tensile strength. The orientation of the film's processing and machine direction and the orientation of the coil set of the film are also considered in arriving at a matched layer set.
